Description

An assembled ground pipe pile steam curing table Technical Field

[0001] This utility model belongs to the field of pipe pile steam curing technology, specifically relating to an assembled ground pipe pile steam curing platform. Background Technology

[0002] PHC pipe piles, or prestressed high-strength concrete pipe piles, are hollow cylindrical precast concrete components produced using a pre-tensioned prestressed centrifugal molding process and steam curing at approximately 10 atmospheres (1.0 MPa) and 180°C. Standard section lengths are 10 meters, with diameters ranging from 300 mm to 800 mm, and concrete strength grades ≥ C80. Besides standard section lengths, non-standard pipe piles of varying lengths, diameters, and shapes are also available. Steam curing of the pipe piles is primarily carried out in steam curing tanks. During the initial plant design, a certain number of steam curing tanks are excavated on the ground. The pipe piles are then hoisted into the steam curing tanks using a crane, and the tanks are covered. The steam curing tanks are connected to a steam supply system and filled with steam at a specific temperature. A certain steam pressure is maintained within the tanks, and the steam curing process is completed after a specified design period. Traditional steam curing tanks require prior ground excavation. Pipe pile production is typically scheduled based on order volume, often resulting in long queues for steam curing during peak seasons or when companies expand. The insufficient number of steam curing tanks severely impacts pipe pile production demand. Unlike other equipment, existing steam curing tanks cannot be readily expanded in terms of capacity through equipment purchases. Therefore, it is necessary to design an emergency steam curing equipment for pipe piles that can be quickly assembled as needed and meets the steam curing requirements of different pipe pile models.

[0022] As shown in Figures 1-5, an assembled ground pipe pile steam curing platform includes a support platform on the ground and a detachable steam curing hood covering the support platform. The upper surface of the support platform is provided with a placement groove 1 for placing pipe piles. The support platform is composed of several support platform units assembled sequentially. Each support platform unit includes two end support platform units 2 and several middle support platform units 3. The end support platform units 2 and the middle support platform units 3, as well as adjacent middle support platform units 3, are detachably connected by several connecting structures 4 located outside the support platform. The steam curing hood is composed of several steam curing hood units assembled sequentially. Each steam curing hood unit includes two end steam curing hood units 5 and several middle steam curing hood units 6. The end steam curing hood units 5 and the middle steam curing hood units 6, as well as adjacent middle steam curing hood units 6, are detachably connected by several connecting structures 4 located outside the steam curing hood. The end support platform units 2 are provided with a steam interface 18 and a pressure relief valve. The steam interface 18 is connected to the placement groove 1. The end support platform unit 2 and the middle support platform unit 3 are assembled together via the connecting structure 4 to form a support platform. Similarly, the end steam curing hood unit 5 and the middle steam curing hood unit 6 are assembled together via the connecting structure 4 to form a steam curing hood. The pipe piles to be steam cured are stacked in the placement tank 1, covered with the assembled steam curing hood, and high-temperature, high-pressure steam is injected into the placement tank 1 via the steam interface 18 for pipe pile steam curing. The number of middle support platform units 3 and the number of middle steam curing hood units 6 are selected according to the length of the pipe piles to form a steam curing platform of the required length. When the production capacity of the steam curing tank meets production needs, the steam curing platform can be disassembled and used for later use, without occupying production space.

[0023] Furthermore, the connecting structure 4 includes two fixed shafts 7, each with a rotating plate 8 mounted on it. One end of each rotating plate 8 has a through hole, and the other end has a hook 9. The rotating plate 8 is movably mounted on the corresponding fixed shaft 7 through the through hole. A clamping nut 10 is mounted on each fixed shaft 7. One fixed shaft 7 in the same connecting structure 4 is located on the end support platform unit 2, the middle support platform unit 3, the end steam curing hood unit 5, or the middle steam curing hood unit 6. The other fixed shaft 7 is fixed to the connected middle support platform unit 3 or the middle steam curing hood unit 6. By rotating the two rotating plates 8, the hook 9 engages with the other fixed shaft 7, and the clamping nut 10 is tightened. The hooks 9 on the two rotating plates 8 in the same connecting structure 4 can be oriented in opposite directions.

[0024] Furthermore, the upper surface of each steam curing hood unit is provided with T-shaped lifting lugs 11. The lifting lugs 11 facilitate the use of cranes or other tools to lift and assemble the steam curing hood unit. After the steam curing hood is assembled, it can also be lifted by cranes or other tools and placed on the support platform.

[0025] Furthermore, a leak-proof nylon membrane 12 is laid on the support platform, with its middle portion fitting into the placement groove 1. A drainage groove 13 with a valve is provided on the end support platform 2, and the drainage groove 13 connects to the placement groove 1. The leak-proof nylon membrane 12 is laid in the placement groove 1, with both sides extending out of the groove 1. The membrane 12 is pressed down by the steam curing hood, and both ends extend into the drainage groove 13. This prevents condensate from flowing out from the gaps between the support platform units, guiding the condensate to the drainage groove 13 for periodic discharge. The leak-proof nylon membrane 12 also collects concrete leaking from the pipe pile mold, facilitating cleaning of the steam curing platform.

[0026] Furthermore, a temperature sensor and a pressure sensor are installed on the end support unit 2. The temperature sensor senses the temperature in the placement groove 1, and the pressure sensor senses the air pressure in the placement groove 1.

[0027] Furthermore, the central steam curing hood unit 6 is equipped with a steam auxiliary heating system, which includes a heating resistance wire located inside the steam curing hood. A power socket is located on the outside of the central steam curing hood unit, and the power socket is electrically connected to the heating resistance wire. Any power socket on the central steam curing hood unit 6 can be selected to connect to production power to maintain a stable temperature inside the steam curing table.

[0028] Furthermore, the connection point of the end support unit 2 for connecting with the middle support unit 3 is provided with a sealing gasket, and the two ends of the middle support unit 3 are respectively provided with sealing rings. The connection point of the end steam curing hood unit 5 for connecting with the middle steam curing hood unit 6 is provided with a sealing gasket, and the two ends of the middle steam curing hood unit 6 are respectively provided with sealing rings.

[0029] Furthermore, the upper ends of both sides of the placement groove 1 are respectively provided with inclined flared slopes 14, and the lower ends of the inclined flared slopes 14 are provided with support platforms 15 for supporting the steam curing hood. The inclined flared slopes 14 are beneficial for positioning the steam curing hood during hoisting.

[0030] Furthermore, the lower surface of the support platform is provided with a support portion 16 into which the placement slot 1 can be inserted. The two sides of the support portion 16 are respectively provided with constricting inclined surfaces 17 that match the inclined flared surface 14. When the steam curing platform is not in use, the support portion 16 facilitates the stacking and storage of the support platform units.

[0031] Furthermore, the support portion 16 is equipped with pulleys. The support platform unit can be easily moved using the pulleys.

[0032] It is worth mentioning that the technical features of heating resistance wire, temperature sensor and pressure sensor involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent.
